15.3 ConneCtIng the outDoor temperature sensor probe
15-3. connecting the outdoor temperature sensor probe
The SIEMENS model QAC34 outdoor temperature sensor probe (optional accessory) must be connected to terminals 7-8
of terminal board M2 in figure 11.
The procedures for setting the gradient of the temperature curve "kt" vary depending on the accessories connected to
the boiler.
a) Without accessories:
The temperature curve "kt" must be selected by setting parameter H532 as described in section 17 "setting the boiler
parameters".
See graph 1 for selecting the curve referred to a room temperature of 20°C.
The chosen curve can be shifted by pressing the
displayed by pressing the
curve Kt=15.
Increase the value displayed if the room temperature required is not reached inside the premises for central heating.
